Tiled Upscale #4549

Open Millu opened 1 year ago

Millu commented 1 year ago

Summary

Tiled upscaling is method of upscaling where an image is subdivided into multiple images, with an upscaling pass ran on each image and then masked back together to achieve an upscaled image with lower memory usage than upscaling the entire image in a single pass.

Similar to Ultimate SD Upscaler with Comfy/A111

Intended Outcome

InvokeAI supports tiled upscaling in the Linear UI & in nodes
User should have the ability to choose the number of tiles
User should have the ability to choose the scale factor (up to 8x)

It is also would be great if they also added StableSR support for Tiled Upscale. StableSR requires connect an addition model for it (such as webui_768v_139.ckpt), and provides excellent detail with SD 2.1 models

There is a version of this now as part of my xygrid nodes. https://discord.com/channels/1020123559063990373/1133465385182699582

And has been discussed a fair bit in a embiggen thread in the nodes-chat forum on discord. Along with discussion of future updates of seam blending.

It would probably need a bit of work for it to be part of core but it might be as a starting point or at least provide some ideas for discussion.
